Intra-arterial waveform analysis: a study of senior nurse knowledge in a general intensive care unit

The aim of this small-scale study was to assess what knowledge senior nurses within a general intensive care unit (GICU) had in relation to intra-arterial blood pressure (IABP) waveform analysis. Its core objective was: To assess what knowledge was held by the senior nursing team with regard to arterial waveform interpretation, arterial waveform morphology and the technical aspects associated with arterial waveform monitoring.

Synonymization of key pest species within the Bactrocera dorsalis species complex (Diptera: Tephritidae): Taxonomic changes based on a review of 20 years of integrative morphological, molecular, cytogenetic, behavioural and chemoecological data

Bactrocera papayae Drew & Hancock, Bactrocera philippinensis Drew & Hancock, Bactrocera carambolae Drew & Hancock, and Bactrocera invadens Drew, Tsuruta & White are four horticultural pest tephritid fruit fly species that are highly similar, morphologically and genetically, to the destructive pest, the Oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae). This similarity has rendered the discovery of reliable diagnostic characters problematic, which, in view of the economic importance of these taxa and the international trade implications, has resulted in ongoing difficulties for many areas of plant protection and food security. Consequently, a major international collaborative and integrated multidisciplinary research effort was initiated in 2009 to build upon existing literature with the specific aim of resolving biological species limits among B. papayae, B. philippinensis, B. carambolae, B. invadens and B. dorsalis to overcome constraints to pest management and international trade. Bactrocera philippinensis has recently been synonymized with B. papayae as a result of this initiative and this review corroborates that finding; however, the other names remain in use. While consistent characters have been found to reliably distinguish B. carambolae from B. dorsalis, B. invadens and B. papayae, no such characters have been found to differentiate the latter three putative species. We conclude that B. carambolae is a valid species and that the remaining taxa, B. dorsalis, B. invadens and B. papayae, represent the same species. Thus, we consider B. dorsalis (Hendel) as the senior synonym of B. papayae Drew and Hancock syn.n. and B. invadens Drew, Tsuruta & White syn.n. A redescription of B. dorsalis is provided. Given the agricultural importance of B. dorsalis, this taxonomic decision will have significant global plant biosecurity implications, affecting pest management, quarantine, international trade, postharvest treatment and basic research. Throughout the paper, we emphasize the value of independent and multidisciplinary tools in delimiting species, particularly in complicated cases involving morphologically cryptic taxa.

Psychosocial presentation of revisional LAGB patients: A qualitative study

This qualitative study offers insight into the experiences, expectations, perceptions and beliefs that may lead to laparoscopic adjustable gastric band patients’ failure to achieve expected weight loss and seek revisional bariatric surgery. The 23 participants from two sites were interviewed and data were analysed from a grounded theory methodology in order to build a causal model. Analysis of participants’ reports identified ‘unrealistic expectations of the LAGB’ as the core category. Additionally, the restriction of the band had a negative impact on participants’ social interactions, leading to feelings of deprivation and, thus, to a desire for reward from food choices and consequently an increase of consumption of high-calorie-dense foods. These foods were chosen because of their specific texture or ability to provide reward. The resulting increase in weight or failure to achieve excess weight loss, led to feelings of shame and loneliness and emotional eating resulting in increased the consumption of rewarding foods. Thus, identifying unrealistic expectations of laparoscopic adjustable gastric band (LAGB) and emotional eating behaviours are important in those who are present initially for primary bariatric and revisional bariatric surgery, as they may contribute specifically to these patients’ weight regain and consequent failure to achieve excess weight loss.

Effects of SEBS-g-BTAI on the morphology, structure and mechanical properties of PA6/SEBS blends

Styrene-b-(ethylene-co-1-butene)-b-styrene (SEBS) triblock copolymer functionalized with epsilon-caprolactam blocked allyl (3-isocyanate-4-tolyl) carbamate (SEBS-g-BTAI) was used to toughen polyamide 6 (PA6) via reactive blending. Compared to the PA6/SEBS blends, mechanical properties such as tensile strength, Young's modulus, especially Izod notched strength of PA6/SEBS-g-BTAI blends were improved distinctly. Both theological and FTIR results indicated a new copolymer formed by the reaction of end groups of PA6 and isocyanate group regenerated in the backbone of SEBS-g-BTAI. Smaller dispersed particle sizes with narrower distribution were found in PA6/SEBS-g-BTAI blends, via field emitted scanning electron microscopy (FESEM). The core-shell structures with PS core and PEB shell were also observed in the PA6/SEBS-g-BTAI blends via transmission electron microscopy (TEM), which might improve the toughening ability of the rubber particles.

Développement de la sensibilité des neurones du collicule supérieur à la durée de la stimulation auditive

Chez plusieurs espèces, les neurones auditifs sensibles à la durée de la stimulation sont présents au niveau des collicules inférieurs. Toutefois, le décours temporel de leur développement fonctionnel est inconnu. Étant donné que le collicule supérieur est l’un des principaux relais sous-cortical impliqué dans l’intégration des stimuli audio-visuels, nous voulons déterminer si le collicule supérieur du rat contient de tels neurones et s’ils sont sensibles et sélectifs à différentes durées de stimulation auditive. De plus, l'originalité de cette étude est de déterminer les étapes de leur maturation fonctionnelle. Des enregistrements neuronaux unitaires et extra-cellulaires sont effectués dans le collicule supérieur de rats juvéniles (P15-P18, P21-P24, P27-P30) et adultes anesthésiés. La sensibilité à la durée est déterminée lors de la présentation de bruits gaussiens (2-10 dB SPL au-dessus du seuil) de durées variables (3-100 ms). Seulement un faible pourcentage des neurones du collicule supérieur est de type passe-bande (3-9% des neurones parmi les ratons et 20% chez les rats adultes). Une différence significative de la distribution entre les différents types de neurones auditifs sensibles à la durée est présente au cours du développement: les neurones de type passe-haut (63-75%) sont présents en majorité chez les groupes juvéniles alors que 43% des neurones sont de type insensible à la durée de la stimulation auditive chez les rats adultes. Ces résultats montrent qu’une population importante de neurones auditifs du collicule supérieur du rat est sensible à la durée des signaux sonores et qu’un développement fonctionnel important survient au cours du premier mois postnatal.

Design, testing, and simulation of fibre composite leaf springs for heavy axle loads

This paper summarizes the design, manufacturing, testing, and finite element analysis (FEA) of glass-fibre-reinforced polyester leaf springs for rail freight vehicles. FEA predictions of load-deflection curves under static loading are presented, together with comparisons with test results. Bending stress distribution at typical load conditions is plotted for the springs. The springs have been mounted on a real wagon and drop tests at tare and full load have been carried out on a purpose-built shaker rig. The transient response of the springs from tests and FEA is presented and discussed.

Early adoption of mobile devices : a social network perspective

As mobile devices have become the personal information-processing interface of choice, many individuals seem to swiftly follow fashion. Yet, the literature is silent on how early adopters of mobile devices overcome uncertainties related to shifts in technology. Based on purposive sampling, this paper presents detailed insights into why and how five closely related individuals made the decision to adopt the iPhone before it was available through traditional supply chains. Focusing on the role played by social networks, we analyze how adoption threshold, opinion leaders, social contagion, and social learning shaped adoption behaviors and outcomes. The analyses confirm that network structures impact the early decision to accept the iPhone; they show that when facing uncertainty, adoption decisions emerged as a combined result of individual adoption reflections and major influences from the social network as well as behaviors observed within the network, and, they reveal interesting behaviors that differed from expectations. In conclusion, we discuss implications for both theory and practice.

Working with people who have killed: The experience and attitudes of forensic mental health clinicians working with forensic patients

Forensic mental health (FMH) clinicians sometimes feel unsupported and unprepared for their work. This article explores their experiences of working in a FMH setting in Australia. The research examined the clinical context of clinicians working with forensic patients (FP), particularly those individuals who have killed while experiencing a mental illness. A qualitative, exploratory design was selected. Data were collected through focus groups and individual interviews with hospital and community-based forensic clinicians from all professional groups: psychiatric medicine, social work, psychology, mental health nursing, occupational therapy, and psychiatric service officers. The main themes identified were orientation and adjustment to FMH, training in FMH, vicarious traumatization, clinical debriefing and clinical supervision, and therapeutic relationships. Participants described being frustrated and unsupported in making the transition to working with FP and felt conflicted by the emotional response that was generated when developing therapeutic relationships. Recommendations include the development of programmes that might assist clinicians and address gaps in service delivery, such as clinical governance, targeted orientation programmes, and clinical supervision.
